SY50135Z includes over-temperature protection (OTP)circuitry to prevent the overheating due to the excessivepower dissipation. It will shut down the switching operationwhen the junction temperature exceeds the OTP threshold,about 150°C. In OTP mode, if the junction temperaturedecreases by approximately 20°C, the IC will resume thenormal operation. For a continuous normal operation, providean adequate cooling so that the junction temperature does notexceed the OTP threshold
